Just a GF Bitter from my local bike store,but most of the parts have breaken (and most of the parts are pure shit) so started to change some new parts off... still seat, brakes, rims and fork could be better, and the cranks and bb... and that will cost so much...

 Well, i didn't buy these, got them from my brothers bike. I would not buy them if hadn't got them already. But btw, they really got good grip, tested on ice hockey field!

 do you actually ride in the snow so much you need studded tires>?

 The right word is broken. And about the bike, get new forks, slam your spacers and thats about it.

 Yeah, new fork is on the plan. Maybe just sell the bike like this, and build a new one.

 What kind of bike is that?

 i've got a GF mullet its very similar to your bike. i love mine!
